Understood. But since we will need to drop the open licence, adjustments
are necessary.

should be changed to something like "The Group will collaborate with the
TTCG to add new features to the WebVTT language and prepare annual updates
for the Recommendation."
>
> The WG is free to ask proponents of new features to work them out in the
CG before the WG will take them on. We don't need to say that in the
charter (it would just constrain us). But a well-worked out new feature
that arrives in the WG and can be, or needs to be, directly adopted into
V1, could be taken by the WG *given consensus*.
Since it also needs to be implemented interoperably before going into the
spec, this is not likely the best process. Also, it doesn't help to keep
the spec in the WG and the CG in sync since the CG can't adopt features
from the WG when developed under the w3c doc licence. So, in order to
encourage collaboration and remove the need for forks with new features
also going into the next version spec under development in the CG, I think
the change would be advisable.
Cheers,
Silvia.
